Low-dose aspirin slashed dementia risk by 70% in certain people, study shows. Researchers at Monash University in Australia went back to the ASPREE trial, a large study in which older adults took either a daily low-dose aspirin or a dummy pill (placebo). They analyzed the genetic data of more than 13,500 participants and gave each person a "polygenic score", a combined measure of many small gene variants, linked to how many platelets their blood makes. Platelets are the tiny cells that help blood clot. In the 20% of people with the highest platelet scores, just 1% of those on aspirin developed dementia, compared with 3.3% of those on placebo, about 70% lower risk. Earlier trials found aspirin didn't prevent dementia when everyone was considered together, so this points to a hidden group who might benefit, and to platelet biology as a new lead in dementia research. The signal wasn't tied to known Alzheimer's risk genes. But the same high-score group also had more major bleeding on aspirin, 4.4% vs 2.1% on placebo. This is a subgroup finding that still needs confirming in a dedicated trial. Do not start taking aspirin to prevent dementia on your own: daily aspirin can cause serious bleeding, so talk to your doctor first. source: Fransquet, P. D., Yu, C., Tran, C., Hussain, S. M., Brodtmann, A., Tonkin, A. M., Nelson, M. R., Ryan, J., McNeil, J. J., & Lacaze, P. (2026). Platelet count polygenic scores may modify the effect of aspirin in primary prevention of dementia.

Scientists watched the brain flip between a face it was seeing and a face it was hiding, about 15 times every second. Researchers at UC Berkeley, led by Janis Hesse and Doris Tsao, recorded thousands of individual neurons in two rhesus monkeys using ultra-thin electrode probes. The monkeys looked at a trick display: one face was shown to one eye, then a second face was flashed to the other eye. The flashed face is the one people consciously see, while the first is still there but pushed out of awareness. Instead of simply silencing the hidden face, the same face-sensitive cells in the temporal and frontal lobes alternated between the two, spending about 60 milliseconds on each before switching back. That matters because scientists have long hunted for a specific spot where consciousness lives. These results hint that timing, not just location, decides what reaches awareness: the brain keeps both options alive and rapidly picks which one gets the spotlight. It's an early preprint, not yet peer reviewed, based on two monkeys. source: Hesse, J. K., Lanfranchi, F. F., McGrory, C., Shi, Y., Engel, T. A., & Tsao, D. Y. (2026).
